,IMPROVEMENT IN THE MODES OFATTACHING PIPES TO S |NKS, DR'AINS, &c.

:The Schedule referred to in these Letters Patent and maldng part of thesame.

`To all whom it mwy concern y Beit known that I, AARON B. N OTT, ofFairhaven, in `the county of Bristol and State of .Massachusetts,

have invented aheiv and improved Mode of Attach-- Figure 2 is a topviewof the basin `covered bv itsv perforated plate.

Figurer-3 is a top 'view of the basin, with two of its` perforatedplatesremoved. r

Figures 4, 5, 6, and 7 are views, in detail, of parts which belong tothe basin. i

Figure 8 is a diametrical sectionthrough the basin, showing a thin.metal pipe applied to it. 1 Similar letters of reference indicatecorresponding parts 'in the several figures; On the 23d dayof November,A. D. 1869, Letters IEatent-of the United Stateswere grantedtoine for`a'n'invention which was designed for securing waste- Vpipes tokitchen-sinks. `In the schedule making part of my said Letters Patent itis set forth that thein-` vention consists in securing'awaste-pipe tothe upper side of a concave depression, which is' made into the bottomof a sink, by means of a clamping-cap, and a packing-ring, which thesaid bowl or depression was adapted to receive.

My present invention is applicable to sinks for domesticpurposes,whether made Vof iron, wood, soapstone, or other material;also, to gutters for houses, to drains, cesspoolaand to tanks of variouskindsi It consistsp 1 i First, in a lauged bowl or basin, having acentrally- Y raised rim in its bottom, surrounding a double annular seataboveand below, which latter are fastening-lugs,

saidiseat being adapted to receive on its upper side a yflange which isformed on a packing-tube or collar, and

on its bottom side the end rof a wastepipe, 'and a nut for securing thepipe in place, as will be hereinafterY explained. a.

. Second, in a double seat, having lugs above and below it, adapted toreceive and hold iirmlyin place upon v its upper side a hangedpacking-tube, and also to receive and hold in place to its bottom side awaste-pipe and the retainipg-nnt thereof, whether said seat and lugs becast in adepression which is formed on a tank,

or whether the said parts `bec-ast separately and afterv ward secured toa tank or other object, as will be hereinafter explained.

Athe bottom of fh nge e.

, To enable others skilled in the 'art to understand my invention, Iwill describe its construction and pperation. y

' I the accompanying drawing- A representsa bowl or basin, which is notcast with a tank, and which may be circular, rectangular, or of anyother shape adapted to theobject for which it is designed.

This bowl is constructed with a iiange, a, around itsv margin, which isperforated, for allowing it to be secured'above or beneath the bottom ofa tank or other object.

An annular depression, `c,is made in the bottom of I the bowl A, which'depression surrounds an annular elevation, d; and within thiselevation, below its upper margin, is an annular flange, e, the upperand bottom sides of which are smooth and horizontal, and.; formtwoseats.

Inside of the bowl, and rising from the annular depression c, are twoover-hanging lugs, li i, which are ar. ranged diametrically voppositeeach other, andslightly overhang the flange e, as shown in gs. l and 3.

The upper side of the flange e receives through it, and supportsavfianged tube, F.

T-he bottom side of said seat e receives against it the upper end of awaste-pipe, P, and the upperl vanged end of a confining-nut, N, which isforced home against the4 seat by the action oi' the tapering anges O Oupon two lugs n u. f p

The lugs n n are cast on the bottom of the howl A, diametricallyopposite 'each other, and serve, in comv junction with the two taperingilanges U 0,to allow -the upper end of pipe P to be forced snuglyagainst It will be seen that the upper end of pipe P is spread out so asto giveit a flaring shape, and that the in' telior of the nut- N is madeto correspond to such' shape, .thus firmly securing the pipe P into th'enut, audpreventing its detachment from thejbowl Acxcept by iirstdetaching the said'nnt.

The hanged tube F is constructed with a tubular portion, J, that extendsdown through the opening,

surrounded by the seat e," and ts snugly into kthe pipe l?.

This tubular portion J terminates at its upper end in a perforateddiaphragm, which is surrounded by a flange, f, which has an annular rib,j, formed on its .bottom side, that is forced down hard upon the upperside of the flange c, when the iiangeg` is confined in place beneath thelugs i i, as shown in figs. 1 and 2.

v The notches p 11, .into theedge ofthe iiangc f, allow this fiange tobe adjusted beneat-hthe lugs i, i.

B is a perforated'strainer-disk, which is inserted into the bowl A, andsupported upon a shoulder, formed in this bowl near its upper margin.

Beneath this strainer is another strainer, which is slotted at g g, sothat it will receive the upper portions of the lugs t' -i and rest downsnugly in place.

This strainer is doine-shaped centrally. so as to cover the perforatedend ci' tube J, and it has an ninnlar depression near its circumference,which is perforated and received more or less into they annular portione of the bowl A, as shown in the accompanying.,r drawing.

ln iig. 8 a thin metal pipe, R, is represented secured to the bowl, witha iange on the upper endof this pipe resting upon the upper side of the`flange e, and confined down in place by means of the iange which is outhe upper end of the tube J. p

It will be seen, from the above description, that I am enabled to attachpipes of dilcrent kinds to a bowl,

A, in a very secure manner, and without liability of" leaking, and alsoto readily detach a pipe from the bowl at pleasure, for cleaning out.repairing, 85e.

It will also be seen that the bowl A may be made separate from theobject for which it is designed, and secured either to the upper orbottom 'side ot'such 0bject.

It will also be seen that pipes may be attached, as above described, todepressions cast in the bottoms of tanks and other objects, instead ci'to the detachable bowls.

VBy my invention I 'greatly facilitate the process Aof molding, as Iobviate the necessity of setting cores, which, under the old plans, arenecessary to be used to produce the pipesou the bowls.

Having described my invention,

What I claim as new, and desire to Secure W by Letters Patent, is

1,."lhe annular double seat-ange e, formed within a raised portion, d,of the flanged bowl A,'in combination with lugs t in n, substantially asand for the purposes described;

2. The iianged tube F, constructed as described, and combined with thelseat c, substantially as described.

3. The flanged nut N and pipe P, in combination with the flange e andlugs n n, and with the flanged tube F, substantially as described.
